High Pressure UV Curing lamps (also known as Metal Halide lamps) are used in a wide variety of applications, such as:
- Pharmaceutical /Medical/Dental
- Photo Polymerization
- Curing of paints/lacquers
- Curing of adhesives
- Sewer rehabilitation
- Food and Beverage
Typical High Pressure (HP) UV curing lamps (Mercury) have short wavelength outputs that peak at 254nm and 365nm. A basic mercury HP lamp will emit energy in both these ranges, but its strongest emission is in the short wavelengths. Other applications, most often in the reprographic industry, call for higher wavelengths such as 385nm and 417nm.
To alter the spectral output and access these additional radiation peaks – additive lamps are created by dosing the lamps with heavy metal compounds. Commonly requested additives for HP UV curing lamps are Gallium-Iodide (400 -450 nm) and Iron-Iodide (350 – 400 nm). Other additives are available upon request dependent on your specific application.
